Why will my rigid body objects not come to a rest after landing in a bowl?
The solution is quite simple! you need to enable deactivation on the chip meshes.



If they don't settle down fast enough, raise the linear and angular velocities. I'd especially recommenced the angular velocity (amount of rotation). 

How this option works is that when the rigid body gets still enough, it is deactivated and stops moving.

For you particular simulation, values around 2.6 seemed to work well.
